We are spending the day trying to hack an AC motor for use at a trade show. We do not need to control the speed of the motor, just direction.

We are running into trouble today controlling both directions. We were able to control just one direction before with two relays. This time, we added two more relays and the motor stops working on either direction. The problem we’re trying to solve today is to control both directions at its full speed.

Here are some steps that we took and image reference:————————————————————————->We were able to control the SSRs with arduino and the code below, You can see from the video

Marcela and Eric Rosenthal colored it and drew the connections from the pendent switch to Solid State Relays and an Arduino:

The wiring look like this:

Here's the code that we're using:

/* this code only run both direction once when it starts, then the ac motor stops working completely with arduino after that.. we can still operate the motor with its pendent switch. We had also observed a loud noise coming from the motor during the time of the delay function */

//Another experimental code that we’re working on add a equation for the 25% duty cycle, still it’s not working with the motors but it can controls the solid state relays
